KJWW's vice president, Warren Lloyd, PE, LEED® AP, describes the geothermal system that KJWW designed for Sherman Hospital in Elgin, IL. The 18-foot deep lake provides 2,450 tons of cooling, with room to expand to 3,400 tons as the campus grows. Loops of piping structured in 30'x8' pre-assembled grids are floated to the bottom of the lake. The system features 177 miles of polyethylene pipe, 175 heat exchangers and 757 water-to-air heat pumps to circulate energy throughout the facility.
